I would like to start my point with a counter question as to which types of construction projects, Private or Public? Each have their own dynamics which play definitive roles that ultimately affect the delivery of the project.
In order to understand the extent of the problem, these two environments need to be isolated and compared with each other to determine why do some projects succeed and others fail. The traits that lead to the success of projects on either side can be contextualized and applied to failing and future projects.
The project life cycle is the same for any project, so the success or failure of projects does not rely on one element within the life cycle. It is a result of incremental incidences that eventually sum up to the success or failure of a project.

Political interference, coupled with weak accountability throughout the project lifecycle, is a significant contributor to the failure of construction projects in South Africa. Contractual provisions are often difficult to enforce against politically connected contractors, as they may escalate matters to senior officials who have the authority to override or influence contractual decisions.
Factors Affecting SA construction projects and why the same are failing:
1 Construction Mafia - Demanding 30% of contract value causing disruption.
2 Contractors are not paid in terms of the contract and in time.
3 Lack of skills from relevant consultants.
4 Current economic conditions
